Title: Water balance economy - in air coater interaction systems by liquid level and hardness control
Inventor: STEIGERWALD HELMUT
IPC: C02F9/00
Filed: 1979-06-05
Abstract: The water balance is controlled in plants with a gas/water interaction, specially in gas scrubbers and cooling towers, by liquid level monitors and hardness detectors. The maximum level is restored by fresh water, softened by ion exchange resin, when a maximum concentration of salts is exceeded. The hard water is removed until a minimum level is reached. The removed amount is replaced by an anticorrosion agent. This reduces the consumption of water and of anti-corrosion agent to the minimum required for a reliable function of the system.
